With keypad lock, you can receive calls and
the handset prompts you to answer. With
phone lock, the handset is shut down and
calls/alerts go to voicemail.
When your handset receives a Private or
Talkgroup call, the keypad lock will unlock for
the amount of time you selected. If you do
not answer the call in that amount of time, the
keypad will automatically lock again. If you
answer the call, and once the handset returns
to the handset idle state, the keypad lock will
be automatically reengaged.
